Toall fwiome't may Concern.' u A Be it rknown lthat we,,l HARRY KAUFE-l MAN and Bonner J. F onMAN, citizens `of the United States, .residingA at .VVilmingtom ;in

the county of New Castle'. and State `of DelafL ware, have invented new and useful lm` provenientsin Switches', ofwhich the following is a specification. .c u This invention relates to Switches, and comprehends a novelconstruction of means for connecting the switch points for simultaneous adjust-ment and holding said points in fixed relation to thek rails of the track when the switch is held yopened or closed The nature and advantages of the invention will be better understood when the following detailed description is read in connection with the accompanying drawings, the invention residing in they construction, combination, and arrangement of parts as claimed.

In the drawings forming part of this ap plication, like numerals of reference indi,- cate similar parts in the several views and wherein Figure 1 is a top plan view of the switch constructed in accordance with the present invention` Figure 2 is a sectional view taken on line 2-2 of Figure 1.

Figure 3 is a detail view of the stationary block associated with each rail.

Figure et is a view taken at right angles to to the rails 10 when the switch is eitherl opened or closed, we employ a pair of blocks of the character illustrated in Figures 3 and 5, which are designed to eliminate the dependence of spikes in the wood to hold the rails in place. As illustrated, there is a pair of these blocks used in conjunction with each rail 1() and the switch point 11. The correspondingkblocks,12vIofeach pair. are

signedgtoyreceive the baseoffthefrails as shown in Figure 2,1 these blocks being' arstationaryV with'respect thereto, While the corresponding blocks 13 `arearranged at the, mnersides of the rails 10; but-secured to the j switch pointsl-jlll` f'The `blocks 12 and ,'13 are ranged at the -outsiderofuthe rails-and held gf providedwith alined: portionsor passages 'i f 14 and 15 respectively to accommodate a bolt 16which yis utilized to connect the blocks of each pair together. The bore 14 -of the block 12 has an enlarged portion in which is threaded a sleeve-like memberl 17, this member beinginteriorly threaded as at 18 to accommodate the threaded extremity of thebolt 16. The bore 15 ofthe block'lis y provided with an enlarged portion which receives the head 19 of the bolt 16, the head 4 being provided with an opening 20 for a purpose to be presentlydescribed. The' switch points' 11 are associated by means of a connecting bar 2,1 which is secured to the points y are however, designed to embracethe other side of the base of the rail, so that when one one pair of blocks isassociated with its adjacent rail, the particular switch point is` held firmly in contact with the rail. Each block 12 lis provided with an apertured offset portion 28, and journaled in these portions is an operating shaft 24, which is preferably made up of a number of sections connected by universal joints 25vas shown. The operating shaft has'mixed thereto pinions 26 reason of which fact, the blocks are arranged. to move lwith theswitch pointsll toward,y and away from the rails 10. The blocks 13 which mesh with gears 2,7 carried by the sleeve-like members 17. The shaft 24 is adapted to be rotated by any suitable power, and manifestly, whenv the shaft is rotated, the bolts 16 moving longitudinally of the sleeve-'like members effect a 'simultaneous adjustment ofthe switch points to either open or close the switch as the case maybe.v

While it is believed that from the foregoing description'the nature and advantages of the invention will be readily apparent,

we desire to have it understood that we do not limit ourselves to what isherein shown signed to embrace the rail, the outermost.-

bloc-k of each pair being associated with the rails, the innermost blocks of each pair being carried by the switch points, and means `rconnecting saidsvvitch points for simultaneous adjustment, sleeve-like members rotatably litted inthe outermost blocks of each pair, said members being interiorlyy threaded, adjust-ing elements threaded in said sleeves and connecting the respective blocks of each pair, andmeans for rotating said sleeves -for the purpose specified.

The combination Wit-h the rails of a track and movable switch points, of abar connecting said points for simultaneous adjustment, a pair yof blocks for each rail, said blocks being designed to unitedly embrace said rails, the outermost blocks being secured to the rails, means for securing the innermost blocks to the 'switch points for movements therewith, a sleeve-like member rotatably ttedin each o'l said outer blocks, said sleeve members being interiorly threaded, adjusting elements connecting'thc blocks of the respective pair and adjustably received by said sleeves, means for rotating said sleeve to effect an ladjustmem; of vthe switch points, said means including an operating shaft mounted for rotation, pinions carried by said shaft, and gears secured to said sleeves and meshing with said pinion.

Inv testimony Whereof'we vailix our signatures.
